Invariant, super and quasi-martingale functions of a Markov process

Iulian Cîmpean, Lucian Beznea

We identify the linear space spanned by the real-valued excessive functions of a Markov process with the set of those functions which are quasimartingales when we compose them with…

From Gaussian estimates for nonlinear evolution equations to the long time behavior of branching processes

L. Beznea, L. I. Ignat, J. D. Rossi

We study solutions to the evolution equation $u_{t} = Δ u - u + \sum_{k ⩾ 1} q_{k} u^{k}$ , $t > 0$ , in $R^{d}$ . Here the coefficients $q_{k} ⩾ 0$ verify $ \sum_{k\geqslant 1}q_k…

Quasimartingales associated to Markov processes

Lucian Beznea, Iulian Cîmpean

For a fixed right process $X$ we investigate those functions $u$ for which $u (X)$ is a quasimartingale. We prove that $u (X)$ is a quasimartingale if and only if $u$ is the dif- fer…
